A sample of an ideal gas in a cylinder of volume 3.67 L at 298 K and 2.47 atm expands to 8.54 L by two different pathways. 
Path a is an isothermal, reversible expansion. 
Path b has two steps. 
In the first step, the gas is cooled at a constant volume to 1.15 atm. 
In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.15 atm until the final volume is 8.54 L. 
Calculate the work for path a. 
Calculate the work for path b. 
a) Work for path a is greater than work for path b. 
b) Work for path a is equal to work for path b. 
c) Work for path a is less than work for path b. 
d) Work cannot be determined with the given information.
